Bold Visuals, Real Escort, Wall Furniture, Bigger Layout, Party

Replaced emoji-based rendering with hand-drawn "bold and blocky" Canvas shapes (rectangular heads/bodies, black outlines, a chef hat or server apron as the only role cue) for every customer, worker, and station icon — no image assets. Seating changed from a fixed-point handoff to a literal escort: a server now physically walks each party to their table rather than just unlocking their movement. Tables are properly spread out (adjacent tables previously computed overlapping seat cells). A wall — built from ordinary, repositionable furniture, not permanent geometry — now separates the kitchen from the dining room, with a doorway. The default layout was rebuilt at ~2.5x its original floor area with a furniture-free cross-shaped walkway after an initial pass turned out to still have a hard chokepoint with no clearance around the door. Guests now arrive as Party groups (1-3 people) that must be seated together and never share a table with a different party, even if seats are free.

Verified this session (see WORKLOG.md for full detail):

• 28/28 automated tests pass, including 3 new tests specifically covering the party-exclusivity rule (seated together at distinct cells; a second party never offered a table already claimed; a table stays claimed until every member has left).
• Balance retuned in three places to match the bigger layout and escort overhead (patience thresholds, SEAT_PARTY job priority, and the default starting crew in main.js) after live testing showed each one, in turn, collapsing throughput to near zero — not assumed correct from code review alone.
• A real bug was found and fixed where any customer leaving a shared table posted a CLEAR_TABLE job unconditionally, even while other party members were still seated there.
• Live UI screenshot confirms parties of varying sizes (1-3) seated at distinct tables simultaneously, with the event log showing party arrivals by name.
